Another Ramadan is upon us, and the Islamic State has called upon Muslims to show their piety during this month by carrying out jihad attacks in the West. In their new video, Muslims are told to “wait and hide for them,” (non-Muslims) “in houses, corners, roads,” and kill them. This is reminiscent of the Qur’an’s exhortation to “kill the polytheists wherever you find them and capture them and besiege them and sit in wait for them at every place of ambush” (9:5), and constitutes yet another reminder that Ramadan is quintessentially the month of jihad.
